Generating MnO2Nanoparticles Using Simulated Amorphization and Recrystallization

Generating MnO2 nanoparticles using simulated amorphization and recrystallization.

Models of MnO2 nanoparticles, with full atomistic detail, have been generated using a simulated amorphization and recrystallization strategy. In particular, a 25,000-atom "cube" of MnO2 was amorphized (tension-induced) under molecular dynamics (MD). Long-duration MD, applied to this system, results in the sudden evolution of a small crystalline region of pyrolusite-structured MnO2, which acts a...

Strain engineering via amorphization and recrystallization in Si/Ge heterostructures

Reversible switching between pressure-induced amorphization and thermal-driven recrystallization in VO2(B) nanosheets

Pressure-induced amorphization (PIA) and thermal-driven recrystallization have been observed in many crystalline materials. However, controllable switching between PIA and a metastable phase has not been described yet, due to the challenge to establish feasible switching methods to control the pressure and temperature precisely. Here, we demonstrate a reversible switching between PIA and therma...

Electrical characteristics of nMOSFETs fabricated on hybrid orientation substrate with amorphization/templated recrystallization method

The use of hybrid orientation technology (HOT) with direct silicon bond (DSB) wafers consisting of a (1 1 0) crystal orientation layer bonded to a bulk (1 0 0) handle wafer provides promising opportunities for easier migration of bulk CMOS designs to higher performance materials. However, the material quality of nMOSFETs regions, which has been undergone amorphization/templated recrystallizatio...

Generating Simulated DT-MRI Dataset

Diffusion tensor magnetic resonance imaging (DTMRI), also known as diffusion tensor imaging (DTI), needs post processing by adequate image analysis and visualization tools. White matter tractography using DTI is becoming a routine MR technique to study white matter properties, connectivity, and alterations of fiber integrity due to pathology. The success of the method depends on the accuracy of...
